The ISO 12137-2011 standard specifies a method for testing the scratch resistance of paints and varnish coatings using a curved pen. The standard is applicable to the evaluation of abrasion performance of single or multi-layer coating systems, helping to compare the performance of different coatings in terms of mar resistance. The standard introduces new definitions and test conditions, updates references, provides a reliable method for evaluating the abrasion resistance of coatings, and provides a standardized test method for performance evaluation and quality control of coatings.
